UNITED STATES SAMUEL II. MGCRACKEN, OF NEW KENSINGTON, PENNSYLVANIA.

ATTACHMENT FOR ACCOUNTING-IIACHINES.

Specification 01' Letters Patent. Patented June 28, 1921.

Application filed March 12, 1920. Serial No. 365,210.

Toall whom it may concern:

Be it known that L'SAMUEL H. Mo-

' CRACKEN, a citizen of the United States, re-v siding at NewKensington, in the county of Westmoreland and State of Pennsylvania,have invented a new and useful Attachment for Accounting-Machines, ofwhich the following is a specification.

Thisiinvention relates to an attachment for use in connection withaccounting machines and more particularly in connection with machinesknown as the Remington In machines of the type mentioned and one inPatent No. 1,298,219 issued to W. D. Sheldon there are used addingdevices or totalizers that are mounted on the actuator rack.

It has been found, however, that where more than two or three of thesetotalizers are mounted on the rack said rack is caused to sag with theresult that the keys will stickand the machine will often lock. At timesthe pressure or strain causes the teeth to break off on the totalizers.

One of the objects of the present invention is to provide means wherebyanumber of to-- talizers can be mounted on the rack without interferingwith the proper operation of the parts due to the causes abovementioned.

A further object is to provide an attachment which is simple andinexpensive, can be applied readily, and will not interfere with theoperation of any of the parts of the machine.

lVith the foregoing and other objects 1n view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and'c-laimed, it being understood that,

within the scope of whatis claimed, changes in the precise embodiment ofthe invention shown can be made without departing from the spirit of theinvention- In the accompanying drawings the preferred form of theinvention has been shown;

In said drawing Figure l is a plan view of a portion of the machine andshowing the attachment in position.

Fig Q is a section on line 2-42, Fig. 1.

Fig. 3 is a front elevation of a portion of the machine with theattachment in place.

Fig. 4 is a side elevation of the attachment. Referring to the figuresby characters of extending in op reference A designates a' portion ofthe, usual carriage or totalizer truck for supporting the totalizers ofa Wahl machine. This totalizer truck or carriage is supported by arms Bosite directions therefrom and having vertical slots C through whichextend small screws D extending from the main or typewriter carriage onwhich the totalizing mechanism is mounted and a portion of which hasbeen indicated at E. The

foregoing structure has been clearly disclosed in the patent to \VebsterNo. 968,103 of Aug. 23, 1910.

The attachment constituting the present invention is in the form of twobrackets each comprising a base 1, an upwardly extending portion 2, anda head 3. The'base is attached b screws or the like to the carriage Ewhile s idably mounted in the head is a screw 4 to the lower end ofwhich is attached the upper end of a coiled spring 5. The lower-end ofthe spring is attached to the arm B there under. A nut 6 engages thescrew 4. and by .means thereof the screw can be raised or creased weightand insure continued correct operation of the parts.

The attachment can be applied readily to machines already in use and byactual practice has been found to materially increase the efiiciency ofmachines thus supplied.

What is claimed is:

In a combined typewriting and computing machine, the combination withthe carriage i of the typewriter, a totalizer truck associatedtherewith, oppositely extending arms on said truck and guides permittinsaid arms a limited vertical movement, of ira'ckets attached to saidcarriage and overhanging said arms, and an adjustable spring connectionbetween each arm and the adjacent bracket.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
